5.1 – Casing
A4 Sheet is attached to the unit for the unit data such
as project name, section number etc. This usually
located on the access cover or door of the fan
compartment.

5.1.1 Casing Panels

Check the AHU panels for any damage. Any dirt or
stains must be removed from the surface to prevent
possible long-term damage. Building debris left on the
roof must be removed. Dirt can be removed with water
and a mild household soap solution. Damage can be
repaired by thoroughly cleaning the affected surface,
then treat and paint as necessary. If applicable check
the sealing joints and repair if required.
5.1.2 - Doors and Access Covers
Check the operation of door handles, locks and
movement of the hinges. For outside installation of the
AHU check the storm cord.
Doors and access covers must always be
closed before starting the unit.

5.1.3 - Flexible Connections

Check that all flexible connections are attached to the
AHU. If necessary, tighten loose screws.

5.1.4 - Earthing

Ensure that the AHU has been earthed correctly and in
accordance with local regulations. A label on the
support frame indicates where the unit should be
earthed.

5.1.5 - AHU Installation and Connection

The floor in the room where the AHU is installed must
be level and flat to prevent connection problems.
In case of multi section unit It is highly recommended
to install common (single channel base through the
AHU) base channel underneath the AHU.
pads/ isolators will be installed underneath this single
channel base.
Before the units are placed against or on top of each
other, the sealing tape supplied must be attached
between the casing sections.
Place the casing sections as close as possible
together before assembly. Pull the casing sections
towards each other by placing the lifting bars first in
one and then in the other casing section. Then pull
both parts towards each other using pull ropes.
The casing sections are connected with the frames
and fixing elements supplied. If the AHU is installed
outside, the roof connecting plate provided must be
installed on the roof and sealed.
